Rotating a Game Object around another controlled game object at a fixed distance

Questions & Answers
1

I am trying rotate a game object around another game object that moves but always maintain the same distance from the moving object. For example, a moon circling a planet. When the planet moves the moon should circle but maintain the same distance. I found this code for rotating around an object but when the "earth" moves the "moon" gets pretty far away.

`var degrees = 10; var target : Transform;

function Update() {

transform.RotateAround (target.position, Vector3.up, degrees * Time.deltaTime);

}`

Any ideas on how to maintain the same distance?

Revised Code:

var rotation : Quaternion;
var radius = Vector3(5,0,0);
var degrees = 10;
var moonCurrentRotation = 0.0;

function Update(){
    moonCurrentRotation += degrees*Time.deltaTime;
    rotation.eulerAngles = Vector3(0, moonCurrentRotation, 0);
    transform.rotation.eulerAngles = Vector3(0, moonCurrentRotation, 0);
    transform.position = rotation * radius + EarthController.earthPosition;
}

I would prefer to use this code (haven't quite familiarized myself with RotateAround :))

rotation.eulerAngles = Vector3(0, currentRotation, 0);
transform.position = rotation * radius + earth.position;
